Check boxes don’t toggle correctly

Tapping an empty checkbox in an issue adds extra brackets and removes the dash, and is no longer recognized as a checkbox by github

(If this hasn't been solved yet)
Are there any other settings you have in GitHawk? e.g., double-tap reactions.
I've found that tapping too quickly on checkboxes triggers the double-tap reaction, which might be a bug on its own and interfere with the checkbox.

Unfortunately I haven't been able to reproduce this either.

Just by looking at the code in IssueCommentSectionController#didTapCheckbox, maybe the checkbox.originalMarkdownRange is somehow being miscalculated, causing the replacement below to be invalid?

let edited = originalMarkdownNSString.replacingCharacters(in: range, with: invertedToken)
